I sent an email to Athom support and they suggested to download and install the full update via the following steps:
- Hold your Homey upside down for 1 minute to enter recovery mode.
- When Homey enters the recovery, go to setup.athom.com with a laptop or desktop.
- Select your preferred language, and click “continue in browser”, shown in grey.
- When “searching for updates” is displayed (or in my case “Homey is up-to-date”), press the ALT button on your keyboard and press on the “Download full update” button that appears.
- When this process is done, press the button “keep your data”, and let Homey finish the setup process.
Following this process steps all my zigbee device are re-established and working again!
